Also, does anyone know how much resistance I should be aiming to have on that connection?

Here's the pic I used:



If I recall correctly, ~65-70ohm worked best. But I ditched it after I read an article about the purpose of vdroop, and then ran into instability.

Just out of curiosity, what's the highest 24/7 overclock anyone has had with this board? And what's the highest overclock anyone has ever hit on this board?

Hey guys, I'm newbee here so please be gentle.

I've been searching the Internet for days to fix my ram problem on this motherboard. I've read a load of pages from this HUGE thread but just can't find what i'm looking for.

Basically I've been trying to get my 4x1GB 800Mhz ram modules running as they should but have had no joy. I can run them at 666Mhz with a slight boost in mem voltage but thats it.

I've been reading about possible fixes via the bios updates but not sure which one to use or how to do this, exactly.

To be honest this is really starting to kill my head and I'm tempted to just buy a new mb or maybe just get 2x2GB of new ram, if this would actually make a difference??

Can someone help me out before I go completely mad. Thanks!

Hey guys, noob here too :P

I pulled off my first (basic, and minor) overclock yesterday on my E6300 with stock air cooling on this board. The only thing I upped was my FSB, and I got my cpu to 2ghz. It's running on about 50-53 degrees under load, but I have a new Zalman CPU cooler on the way now.

The only thing I have questions about is voltages and my ram. I don't have any idea what they should be at and I've tried to research it all but it's really confusing. My voltages would be at normal, because I haven't changed them - along with my ram. I have 2GB DDR2 Geil ram, showing PC2-6400C4 800mhz, but I'm not sure of my timings.. I THINK it's 4-4-4-12. Either that or one lower.

My memory frequency in BIOS is set at 800mhz, and my FSB at 1144, for 2002ghz. Does anyone know what else I should change? If anything?

Hey TriBeCa- check out the latest updates to my sig. That's the very same Q6600 I had running 333x9 @ 1.22V on the old P5N-E I had, Ditched the Ballistix D9GMH 2x1Gb for the 4x1Gb Kingston PC8500, and mmmmm.....happy camper!

Nice to see you again Ravin

Care to race that rig against the new one I just got my supervisor to buy and let me build? It's not in my sig (not technically mine), but check this baby out:

I've actually managed to get my vcore down to 1.2525v and falling...gonna try 1.23 tonight. And I love how well my 4 x 2GB of XMS2 is holding up, rock solid on the ip35 pro.

Only thing is I can't run FutureMark benchies because they don't have an XP x64 version

Thanks a ton. Although I was gonna just pencil mod it... is it the same connection? Haven't got a soldering iron handy

Try increasing vNB to 1.5, or the setting right under that. If you do end up at 1.5, make sure you've at least replaced the stock TIM on the heatsink--preferably replace the sink entirely.

Check out the OCing guide in my sig, that should help

And if you leave voltages on auto and increase FSB, the board will increase voltages on it's own--typically much more than you want it too. It's always a better idea to set them manually.

That's a pretty sweet rig there. Sure I'll take you on, just give me a little time for the HD4xxx release and some cold ambients.

I'm posting 4.0GHz and DDR1200 speeds, and can get the Windows log in screen.....I know I can get it stable.....I know I can...... my 9x multi vs that 7.5x......I can win!

[TriBeCa]

nice.... Have you seen the xbit labs review comparing the q6600 to the q9300? When both are OC'd the benchmarks range from like +20% to -20% advantage, with the q9300 having the edge on a few more of the benches. But if you get up to 4GHz I'm toast... this is a work rig, so no suicide runs, IHS lapping, vdroop mods, etc. etc. That and it's been tough for me to push my RAM too hard, the MCH had enough trouble with these 4 DIMMs at stock (had to add 0.25v just to get the RAM to run at stock).

And what you can't see in the cpu-z link is the 4 500GB drives in RAID10

Oh yeah, and I promise to lose any graphics benchies, cause I only dropped $35 on this graphics card

You're right, on a clock for clock basis, the Q9300 wins due to cache and instruction set differences, but if I can get you by 10% clock speed we're neck and neck. I don't think 4GHz stable is unreasonable for me, although my cooling is holding me back. Temp increases and Vcore requirements above 3.6GHz are exponential and not linear. I've got lots of headroom with Vcore but not temp.

You may be able to decrease Vdimm a little and compensate with an increase in VNB to get your 4 sticks stable. I had to increase my VNB (.08V from 1.41Vto 1.49V) slightly to get my 4x1Gb stable at any speed. I really had to crank it up to get 800MHz CAS3 (like to 1.75V).

Man that 8400GS will crush my 7600GT

[TriBeCa]

we've totally hijacked this thread... sorry everyone. But I think Ravin and I have paid our dues in this thread for long enough to get away with it

I guess I was unclear there--I increased vNB by 0.25v, not vdimm. 2.35v on these DIMMs would be madness without at least active cooling, at least on a work machine.

So considering the futuremark benches are a no-go for me on this rig (until I get fed up and switch to vista, anyway), which ones you wanna use? SuperPi 1M and 32M, and some SiSoft Sandra benches?

I think some of the old guys of the thread deserve that Ive had my E6420 at 3.66ghz but i reckon ive hit the limit my cpu can go.
